My mother told me not to buy water purifier without scrutinizing. I was really confused but when my neighbor gave us information about the demo which is done before purchase.
It really relieved me. I told my family to search Zero b site and check the details and price and whether customer care responds.We were happy about the information we had in hand so booked for an demo. Asked mom to join for the demo and ultimately she finalized the purifier and we got it installed within 3 days. We are using Zero B Eco RO now for more than 2 years and its really good.
